Heating and cooling apparatus

Abstract

A heating and cooling apparatus includes a compressor for pumping a heat medium through a tubing device, a primary heat exchanger coupled to the compressor, a control device coupled to the primary heat exchanger and coupled to a intermediate heat exchanger to control the intermediate heat exchanger either to dissipate heat or to absorb heat. Another control device is coupled to the intermediate heat exchanger and coupled to the compressor and a secondary heat exchanger, to control the heat medium from the intermediate heat exchanger either to flow through the secondary heat exchanger or to directly flow into the compressor without flowing through the secondary heat exchanger.

1 . A heating and cooling apparatus comprising: 
 a compressor for pumping a heat medium through a tubing device,    a first heat exchanger coupled to said compressor, for receiving compressed heat medium from said compressor, for outputting heat,    a first control device coupled to said first heat exchanger,    a second heat exchanger coupled to said first control device, and arranged to have said first control device coupled between said first heat exchanger and said second heat exchanger, said first control device being provided to control said second heat exchanger either to dissipate heat or to absorb heat,    a second control device coupled to said second heat exchanger and coupled to said compressor, and    a third heat exchanger coupled to said second control device, and coupled to said compressor, for outputting cold,    said second control device being provided to control the heat medium from said second heat exchanger either to flow through said third heat exchanger or to directly flow into said compressor without flowing through said third heat exchanger.    
   
   
       2 . The heating and cooling apparatus as claimed in  claim 1 , wherein said first control device includes a flow control valve and a guide tube coupled in parallel to each other, in order to control said second heat exchanger either to dissipate the heat or to absorb the heat.  
   
   
       3 . The heating and cooling apparatus as claimed in  claim 2 , wherein said second heat exchanger includes a first heat exchanging member and a second heat exchanging member coupled in series and coupled to said flow control valve and said guide tube of said first control device respectively, for dissipating the heat or for absorbing the heat.  
   
   
       4 . The heating and cooling apparatus as claimed in  claim 3 , wherein said second heat exchanger includes a throttle device coupled between said first heat exchanging member and said second heat exchanging member.  
   
   
       5 . The heating and cooling apparatus as claimed in  claim 1 , wherein said second control device includes a first flow control valve and a second flow control valve coupled in parallel to each other, and coupled to said third heat exchanger and said compressor respectively, in order to control the heat medium either to flow through said third heat exchanger or to directly flow into said compressor.  
   
   
       6 . The heating and cooling apparatus as claimed in  claim 5 , wherein said second control device includes a throttle device coupled in series to said first flow control valve.  
   
   
       7 . The heating and cooling apparatus as claimed in  claim 1  further comprising an accumulating device coupled between said compressor and said first heat exchanger.
